Description

Digital Video Flashlight Unit

technical field

The utility model relates to a flashlight device, in particular to a digital video recording flashlight device with video recording function.

Background technique

Flashlight is a commonly used electrical equipment. Different flashlights can have different sizes, different structures, different voltages and different lighting brightness, and use different light-emitting devices (such as electric beads or high-power white light-emitting diodes, etc.). Although these various flashlights may not look the same, their basic function is the same, that is, lighting.

A camcorder is also a commonly used electronic device. According to the different image storage methods, it can be divided into two categories: tape cameras and digital video cameras. Regardless of the shape of these products, their basic functions are the same, that is, image recording. Similarly, a camera is also a very commonly used electronic device that can take pictures and record pictures. According to different recording methods, it can be divided into film sensitive cameras and digital cameras.

Flashlights and camcorders/cameras are two different products, and few people associate the two. But in real life, the two are actually closely related and complement each other on some occasions. Because video recording/photographing requires a certain amount of brightness, lighting is needed when the light is insufficient, and a torch is a good video recording/camera lighting source. On the other hand, when using a flashlight, users sometimes need to record/photograph what they see with the flashlight for later use. For example, professionals conduct field inspections at night, maintenance personnel inspect underground pipelines, security personnel conduct night patrols to collect evidence, and traffic police inspect the scene at night, etc. On these occasions, the combination of flashlight and video/photographing device is very meaningful.

In this device, three No. 3 batteries are selected, which can be alkaline dry batteries or rechargeable batteries, such as nickel-metal hydride batteries. Above-mentioned light-emitting device 2, flashlight lighting switch 44, handle 5 and battery 11 have formed a basic flashlight device of this system.

The digital video torch device also includes a camera lens 7, which is mechanically separated and independent from the torch lighting device 1, so as to prevent the light from the torch lighting device 1 from affecting the lens image. There are also some infrared light-emitting diodes 8 around the torch lighting device 1, and when the torch lighting device 1 is not opened, and when taking pictures/photographing at night, these infrared light-emitting diodes 8 just can bring into play the effect of lighting. There is a microphone 9 next to the camera lens 7, which can be used for recording. On the control panel 4 there is a video recording switch 41 and a photographing shutter 42 to realize the control of video recording and photographing. The liquid crystal display 43 of the control panel 4 is mainly used to display the recording/photographing status and the time of recording, as well as related time and date information. The digital video flashlight device also includes a flash memory card (SD card) interface, which is used to insert a flash memory card 10 or a multimedia card (MMC) as a digital image storage device, and is used to store digital images and digital photos, and the USB interface 15 can be used to Connect with PC to read digital image and digital photo information. The camera lens 7 of Fig. 1, control switch, liquid crystal display 41, and flash memory card 10 etc. are the basic components of the utility model video recording/photographing function.

Figure 4 is a schematic diagram of the control panel 4, showing in detail the status of the system. The system status can be displayed by light-emitting diode indicator light or LCD display. This system device adopts the method of liquid crystal display, which can display more relevant status and parameter information for the convenience of users. The first line of the LCD screen 43 is a system status icon, including information such as video recording status indication, flash memory card memory status indication, prompt tone indication, busy status indication, and far/near view status indication; the second line of the LCD screen 43 is time/date Display, in addition to displaying the real time/date, can also display the time of the video recording; the third line of the liquid crystal display 43 is a time setting indication and a date setting indication, so that the user can set the time/date conveniently.

The lower part of the control panel 4 of Fig. 4 is a control button, including a torch lighting switch 44, a video recording/photographing power switch 45 (multiplexing with time setting confirmation), and video recording switch 41 (multiplexing with time setting), Photo shutter 42 (multiplexed with date setting). Wherein the torch lighting switch 44 is independent and will not be associated with other functions. And video recording switch 41 and photographing shutter 42 are multiplexed with the setting of time and date, when power switch 45 was opened, these two switches were used for video recording and taking pictures, and when power switch 45 was closed, then can be used as time and date. The setting of the date will not interfere with each other.

Fig. 5 (a) is the composition block diagram of torch illuminating device, and the structure of this block diagram is the same with the torch on general concept, is made up of light-emitting device 2 (white light emitting diode), torch lighting switch 44 and battery 11. In order to make the torch lighting have a stable brightness, constant current control measures are used in this system device to keep the working current of the torch in the working range of 3.6-4.5 volts unchanged. This measure not only keeps the luminance of the torch stable, but also It is beneficial to protect the light-emitting diode device, prolong the working life of the light-emitting diode, and also make the system adapt to different battery environments, such as alkaline dry batteries and nickel-metal hydride rechargeable batteries, etc., and maintain the same brightness in different battery environments.
